A pure derivation over the vessels we track — the Japan fleet count is the number we hold for the register, not the official register size, so a register we under-sample reads low. Average age is deadweight-weighted (the broker convention) over hulls with a known build year; the over-20-year share uses the same build-year-known denominator. Top owners reflect only our owner linkage, which covers 1% of this register — read the list in that context. Segments use the same classifier as the rest of the platform. Snapshot 2026-08-27.
